It's Alive!
A quick recap... It was eating 6x5 rectifier tubes. Thankfully I had a couple spares around. After a little investigation I found a capacitor I had not noticed (a 16uF electrolytic) concealed behind the original which was left in place and I assumed still attached. Someone had the polarity reversed, which would explain why the set had a bad 6x5 and was sold as "not working." With a replacement capacitor for that one plus the other electrolytic and paper caps, it fired right up! I installed the new eye tube and played with it for a few minutes before shutting down.
My next move is to install a power resistor to drop the input voltage from 123VAC at my outlet to about 105VAC.
Just a little work left on the cabinet, and then it's reassembly time!
